Re: the best long range varmint caliber
My barrel was a 30" to start, then a 29" then a 28", Now, it's a 27" that was sent back and with any luck, I'll never see it again. 9 Twist. Something was wrong with it because with just 1 shot, it filled up with copper and got hotter than any barrel I ever saw before. I couldn't clean it to save my life. I figured it was just a bad piece of steel. Oh well. It's history now.
I still think the 6.5 WSM could be a good round, just, that one put a bad feeling in my gut for the round. If it had EVER shown promise at 1000, I'd probably have persued it. But, it just sucked. It's now a 30 Cal. Regular 300 WSM. This barrel looks nicer already and I've only got 9 shots through it.
Darryl, I was refering to another big gun you had recently that as I remember, was a problem child. When you get right down to it, the 338/416 is probably no more overbore than a 7/300Wby. You have a lot of barrel on the 338 also. I think you could agree that for the most part, a big gun is harder to get to shoot than a small one. Ie, 300RUM or 243Win. Then, the farther away you want it to shoot, the harder it becomes yet.
If you have something that you disassemble and reassemble enough times, sooner or later, you'll have two!
